Harmonic Highlights
- The repeated
Eb07serves as a chromatic passing diminished chord, adding a sophisticated, moving color between various forms of the C tonic (C6 to Cmaj7). - An extensive prolongation of the
Dm7chord creates a sustained ii-minor tension, demanding creative melodic development and building anticipation. - The
Ab7chord, abVI7, leads chromatically toG7(V7), introducing an advanced secondary dominant or tritone substitution flavor that intensifies the pull towards the tonic.
Improvisation Focus Diminished Scale Application
Difficulty Rating 4 (Advanced Intermediate). This reflects the blend of common diatonic harmony with challenging chromatic diminished and bVI7 alterations that require specific scale choices.
